ToaZZ 1071 0112, it may concern.-

Be it known that we, SYDNEY SIMMONS and JOSEPH TULLIDGE, subjects of theQueen of England, residing at London, in England, have invented certainnew and useful Improvements in orRelating to the Cleaning of Caraspeeification.- p

This invention relates to the cleaning of carpets, curtains, and othermaterials or articles by means of a blast of air delivered either,through the materialor angularly upon its surface, so as if not passingentirely through the material to penetrate sufficiently far into it orbetween its fibers or nap to remove dust and such dirt as can be in thatmanner re moved, which in general is found to be praccally all thedirtitcontains Various devices have been used for this purposewith more orlesssuccess; but having found that generally some portions of the materialbeing operated,- upon escape the action of the blast, we have devisedthe following mechanism for carrying out this invention. e prefer toemploy a number of nozzles, a series of nozzles being arranged upon oneor more pipes which, being suitably carried, are enabled or caused torevolve, carrying the nozzles with them. A simple way of constructingthis apparatus is to construct a T of pipe, the cross of the T carryingthe nozzles, and the stem being connected in any convenient manner withthe air-supply, so as to make a sufficiently-tight joint, and at thesame time to allow of the revolution of the T-piece. The nozzles uponthe T would be arranged those on one side of the stem pointing in onedirection and those on the other in the opposite direction,the resultbeing that as the air'escapes through the nozzles the whole T-piece isrevolved on the wellknown principle of the Barkers mill. Any requirednumber of arms may be used, or in stead of the arms a hollow disk uponthe end of the stem, and either carrying any desired number of nozzlesor having any desired number of perforations. Either perforations ornozzles would be arranged so as to direct the air-currents in such amanner as to revolve the apparatus.

In the accompanying drawings, which represent means by which thisinvention may be carried into effect, Figure 1 is a vertical section ofapparatus adaptedfor the purpose.

.Fig. 2 is another vertical section of the apparatus, taken on the line2 2 of Fig.1; and Fig.

*3 shows a modified form and arrangement of the nozzle-heads. pets andtheLike, of which the following is Like letters represent like partsthrough out the drawings.

A represents the casing, which contains the whole apparatus; B, thecarpet to be operated upon; C, the frame-work to support the carpetagainst the blast, that portion D of it againstavhich the carpetrestsbeing preferably formed of open or lattice work, such as crossed leatherbands or the like.

E represents the T-piping, constituting the nozzle-head carrying thenozzles F and G, any suitable form of stuffing box or joint to connectthe T-piece E with the fixed pipe H,

by which the blast is introduced. At the end of the stem of the T-pieceE is a recessed center E, against which bears the pointed center I, soas to prevent nozzle-head E and stationary supply-pipe H being separatedand to provide the necessary bearing for nozzle-head E, as it revolves..Any other suitable fcrm of bearing, may, however, be em ployed.

J is a roller, over which the carpet passes after having been operatedupon by the blast, and A is an opening in the case, through which thecarpet can be withdrawn as finished. The roller J may, if desired, bepositively driven so as to draw the carpet along, and, if necessary, itmay have in connection with it any of the ordinary well-knowncarpet-feeding mechanisms now in common use.

The nozzles F, as shown particularly in Fig. 2, upon the opposite armsof the T may be placed in opposite directions, so as to cause the T torevolve on the principle of the Barkers mill. The various T-picces, ofwhich three are shown in Fig. 2, are also shown connected together bypitch-Wheels K and pitchchains L, the object of which is to allow of theTs overlapping in their revolutions, and thus covering the whole of thecarpet presented to them. This could not be done unless the positiverelation between the Ts were secured, as otherwise they would strike anddamage each other. This arrangement of pitch chains and wheels, or, ifpreferred, of ordinary gearing, enables the Ts, if desired, to be drivenby power instead of by the nozzles, and in such case it is onlynecessary to directly operate one of the Ts, the chains or gearingconveying the motion to the others. Vhen the Ts are driven by power, thedirection of the nozzles upon or openings in the Ts is not material andwould depend rather upon whether it was intended to blow the dustthrough the carpet or other article to be operated upon, or to blow itout of and not through the fabric.

In Fig. 3 are shown a number of hollow disks E, which constitute thenozzle-heads and are provided with nozzles F, which may be setangularly, as in Fig. 2, or otherwise, as preferred. These disks may bedriven on the Barkers mill principle or by power, as before; but thoughthey are arranged, as will be seen from Fig. 3, to overlap so as tocover the whole of the fabric to be operated upon, they need not coupletogether, as there are no flying ends or parts to come in contact. Byadopting the two lines of Ts, as in Fig. 3, they could of course be soarranged as to clear each other and yet to effect the desired object.

The plan above mentioned of carrying the revolving nozzle-heads upon astem is probably the most convenient one and likely to produce as littlefriction as any; but at the same time we do not bind ourselves down tosuch an arrangement, as mechanism could easily be devised embracing allthe essential features of that above described but without the centralstem, and any of the ordinary well-known forms of bearing may beemployedfor the revolving nozzle-head to keep the same from being blown0E without departing from the spirit of our invention.

. We claim 1. In a machine for cleaning carpet, the combination, withthe support having a substantially plane surface over which the carpetpasses, of a head carryinga series of nozzles mounted in bearings andrevolving in a plane parallel and in proximity to thesupporting-surface, substantially as described.

2. In a machine for cleaning carpet, the combination, with a supporthaving a substantially plane surface over which the carpet passes, of aseries of nozzle-heads carrying nozzles and mounted in bearings and re-Volving in a plane parallel and in proximity to the supporting-surface,substantially as described.

3. In a machine for cleaning carpet, the combination, with the supporthaving the substantially plane surface over which the carpetpasses, of aseries of nozzle-heads carrying nozzles and mounted in bearings andrevolving in a plane parallel and in proximity to thesupporting-surface, the paths traversed by the extremes of said headsoverlapping each other, whereby the whole surface of the carpet is actedupon, substantially as described.

4. In a machine for cleaning carpet, the combination, with the supporthaving the substantially plane surface over which the carpet is passes,of a series of nozzle-heads connected by gearing for simultaneousrotation and mounted in bearings and rotating in a plane parallel and inproximity to said supporting-surface, substantially as described.

5. In a machine for cleaning carpet and the like, the combination, withthe casing, of a frame-work C D, rotatablenozzle-head E, nozzles F,stufling box or joint G, pipe H, recessed and pointed centers E I,roller J, pitchwheels K, and pitch-chains L, substantially as described,and illustrated in the accompanying drawings.

In testimony whereof we have hereto set our hands in the presence of thesubscribing witnesses.
